The 100 µV input offset and 5 µA input bias set the measurement floor. ## Package and mounting Housed in an 8-pin SOIC package with a 3.90 mm body width, the MAX4080FASA+ is a surface-mount part that reflows alongside standard passive components. The SOIC-8 footprint is widely used and easy to route; the device's pinout places the sense inputs on one side and the output and supply on the other, keeping the high-current sense traces away from the low-level output signal. ## Lifecycle and compliance It is ROHS3 compliant, so it meets current EU and global restrictions on hazardous substances.","metaTitle":"MAX4080FASA+ Current Sense Amplifier, 250 kHz, 8-SOIC","metaDescription":"MAX4080FASA+ current sense amplifier from Analog Devices. 4.5 V to 76 V supply, 250 kHz bandwidth, 75 µA supply current. -40°C to 125°C.
